Introduction of a quasi-coupled hyperbolic stress-strain constitutive model
Abstract Simplified nonlinear effective stress constitutive models are commonly used in one-dimensional (1D) geotechnical site response analysis for assessment of porewater pressure generation and liquefaction potential in soft soil deposits. This study presents the performance of a 1D quasi-coupled constitutive model termed MRDF + u ( m _odulus r _eduction and d _amping curve f _it using a reduction factor and including porewater pressure generation, u _) at a particular history case (i.e., Port Island, Japan), where liquefaction effects have been reported and the site could be potentially liquefied again. The study included evaluation of the performance of two porewater pressure generation models (Dobry-PWP and GMP-PWP models) coupled into the MRDF + u constitutive model using the Port Island history case. The new coupled model reasonably captures the soil cyclic behavior observed in the history case and may be used to perform effective stress-based 1D site response analysis in engineering practice.
